Exploring Unconventional Entry Holding Patterns- A Dive into Non-Standard Flight Procedures

What Type of Entry Holding Pattern Non Standard?

In aviation, a standard entry holding pattern is a maneuver used by pilots to maintain a specific position while waiting for an approach clearance. However, there are instances when a non-standard entry holding pattern is required. This article explores the various types of non-standard entry holding patterns and their applications.

1. Tailwind Entry

A tailwind entry is a non-standard entry holding pattern used when a pilot is experiencing a tailwind component. In this scenario, the aircraft’s speed is higher than the standard airspeed due to the wind assistance. As a result, the pilot must adjust the entry procedure to ensure the aircraft remains within the designated holding pattern.

2. Headwind Entry

Conversely, a headwind entry is a non-standard entry holding pattern employed when a pilot is encountering a headwind component. In this case, the aircraft’s speed is reduced due to the opposing wind. Pilots must modify their entry procedure to accommodate the slower airspeed and maintain the holding pattern’s integrity.

3. Crosswind Entry

A crosswind entry is a non-standard entry holding pattern used when a pilot is flying into a strong crosswind. This situation requires pilots to execute a more precise entry to avoid complications during the holding pattern. The entry procedure is adjusted to ensure the aircraft remains within the designated pattern and maintains a safe distance from the runway.

4. Low Visibility Entry

In low visibility conditions, such as fog or heavy rain, a non-standard entry holding pattern is necessary to ensure the pilot can maintain a safe and accurate holding pattern. This may involve using additional navigation aids, such as ground-based navigation systems, to guide the aircraft during the entry and holding phase.

5. Airspace Restrictions

Sometimes, non-standard entry holding patterns are required due to airspace restrictions. For example, if an airport has restricted airspace around it, pilots may need to execute a non-standard entry holding pattern to avoid entering the restricted area. This could involve flying a longer entry path or adjusting the holding pattern’s shape to accommodate the restrictions.

Conclusion

Non-standard entry holding patterns are essential for pilots to adapt to various conditions and ensure safe and efficient operations. By understanding the different types of non-standard entry holding patterns and their applications, pilots can effectively manage their aircraft during these situations, contributing to overall aviation safety.
